TEXAS INSTRUMENTS TL1466I handbook
Update: 30 September, 2023
The TL1466I is a six-channel pulse-width-modulation (PWM) control circuit. This device contains reference voltage with a precision of ±2%, a triangle wave oscillator capable of high frequency oscillation up to 0.8 MHz, various protection circuitry and shutdown circuitry. The output regulation voltage for each channel is set by an external resistor divider. Moreover, the output stage is capable of driving a PNP power transistor with high speed. The high frequency/efficiency switching operation eliminates switching loss by using internal over-drive circuitry at the rising edge and with reverse bias connecting external bootstrap capacitor at the falling edge. The MOSFET can be used in parallel with the output diode at channel 1 and 4. This results in further high efficiency operation replacing the constant time with this MOSFET when the output diode is turned on. Furthermore, it operates 2.5 V supply voltage and also has short circuit protection, low power consumption, internal undervoltage lockout protection etc.
